CARD UNIT FOR INDEX SYSTEMS.

Specification of Letters Patent.

Application led September 15, 1915, Serial No. 50,891. Renewed January 4,1917. Serial No'. 140,57.

To all 'whom t may concern.: f Be it known that I, JAMES H. RAND, Jr., a citizen of the United States, and resident of North Tonawanda, in the .county of Ni' agara andState of New York, have invented new and useful Improvements in CardUnits for Index Systems, of which the following is a specification.

This invention relates to card units for card index systems of the overlapping card type, and consists primarily in providing some or all of the cards in the system with a detachable cover or sheath of transparent sheet material superposed on the face of the card, either for protection of the -margin of the card which receives the greatest wear in handling, or for the purpose of a signal, or both. The detachable sheath is also .secured to the card in such mannerthat it constitutes a pocket for holding a removable card or paper insert. These and other features will be vhereinafter more fully described and particularly pointed. out in the claims. Throughout the specification and claims the term card is used to denote any sheet of suitable material and is not to be construed in the limited sense of a sheet of comparatively thick pasteboard..

illustrate several modifications of the inven`- tion,-

Referring iirst to Figs. 1 to 4: A repre#4 sents the card which may in its generalcharacteristics be of usual form. B represents the sheath or cover which is preferably made of transparent sheet celluloid and may be of any desired color.l The sheath is of smaller area than the card and in the form now under discussion covers the lower margin of the cardA which is the margin exposed when a series of similar cards are mounted in a' tongues and sockets. The card A -is proi videdwith a pair of tongues a cut from vthe body of the card and extending outwardly,

. and the sheath-'B is provided with a pair of A complementary holes b. In order to attach the sheath to the card the latter is bent suiiciently to shorten the distance between. the tongues a, and the tongues are then insertedl 1 into the sockets b, whereupon the card A is again allowed to spring 'back into iiatposition, with the tongues interlocked -with the sockets.

The sheath B is open at its upper or -inner edge so that it provides a pocket within which an additional card or paper insert D may be placed. Thus'the indexed .matter may beeither written on the card A, or or the statement of an account, the class orl character of kentries upon the card, etc.

In the form of the invention shown in Figs. 5 to 8, the socket members of the mutually engaging tongues and sockets are shown at a in the card A, while the tongues are shown at b in the sheath B. The

tongues b also extend inwardly instead of outwardly; otherwise the construction and -use of the cards and sheaths is the same as in the form first described. Y

In the form shown in Figs. 9 to 13 the card A is made with a pair of vertical slots a2, vand the sheath B2 is made with a pair of outwardly extending tongues b2 cut from the face of the sheath as shown in Fig. 12, for engaging the sockets a2. The sheath B2 in this modification is also folded around the lower edge of the card A as shown at B (Fig. 11) so that the sheath protects both the vfront and back margins of the card but is still readily removablefrom the card. In the construction shown in Fig. 9 the sheath is divided into three pockets separated by the slots a2 into which. pockets small inserts can be placed. If it should be desired` to have merely one pocket with the form ofv l tongues and slots now under consideration,

the tongues would be cut from the ends of the face of sheath B and the slots a2 correspondingly positioned farther apart in the car In the form shown in Figs. 14 to 17, the sheath B is substantially similar to that shown in Figs. 5 and 7 having inwardly extending tongues b3, while the sockets in the card A .consist of slots or notches a3 cut in from the side edges of the card.

In the form shown in Figs. 18 to 21, the

sheath covers only-part of the card margin, being much `shorter than the. width of ythe card. The sheath B3 is provided with tongues b4 which are inserted into complementary slots a4 of the card A. In this form the sheath` may be placed on any desired part of the card margin which receives the greatest wear in handling, and by the use of colored Celluloid for the sheath it may serve as a'signal in the same Vmanner as in the other forms.

In the form shown in Figs. 22 to 25, the card A is provided with a permanently attached sheath or pocket C preferably made of 'white or colorless transparent Celluloid @overlying the lower margin of the face of the car Nand extending around the lower edge of the card as shown at C. The sheath C is secured to the card A by any suitable means as by a pair of rivets or eyeletsc. The removable sheath B'1 is inserted within the pocket formed by the xed sheath C in front ofthe insert D when the latter is used. As an additional signal for indicatingv secondary information or classification, according to the subject-matter of the card, I

provide the indicator E having a tongue e which engages the edge of the sheath C and is adjustable lengthwise'thereon. It willbe understood that the secondary signal E' might also' be applied to the removable heath of any of lthe forms, as indicated in ig. 1. Je,

The signal E is preferably made of transparent sheet Celluloid lof some color contrasting with the color of the sheath or sheaths, so that although conspicuous it will not obscure matter underneath. Said signal E might be made of other materials either transparent or opaque, without departing from the invention.

I claim:

2. A card for a card index system, and a sheath of transparent sheet material superposed on the face of the card and detachably secured thereto, said sheath being open at one edge at least to form a pocket for an insert between the card and the sheath.

4. A card for a card system, and a sheath of Atransparent sheet material of smaller area than the' card, superposed on the face of the card, covering part of the card and leaving part uncovered, said sheath being detachably secured to the card.

5. A card for a card system, and a sheath of transparent sheet material of smaller area than the card, superposed on the face of the card, covering part of the card and 4leaving part uncovered, said card and sheath being provided with mutually engaging tongues and sockets by which the sheath is detachably secured to the card. l. 6. A card for a card system, and a sheath of transparent sheet material of smaller area than the card, superposed on one margin of the card, said sheath being detachably secured to said margin of the card.

7. A card for a card system, and a sheath iis of transparent-sheet material of smaller area` than the card, superposed on one margin of the card, and said card and sheath being provided with mutually engaging tonguesA detachably secured tothe card margin and open at its inner edge to form a pocket for an insert between the card and the sheath. 10.
